Power Factor Correction (PFC) is a semiconductor device designed to align the phase angle to approach zero between the voltage and current in an AC circuit. The different modes are average current, boundary conduction, continuous conduction, critical conduction, current controlled frequency foldback, discontinuous, and discontinuous conduction with a frequency switching of adjustable and 6kHz to 1.7MHz.
